ABSTRACT:
A splicer for a heat cohering belt has a base supporting a lower platen frame. A heated lower platen is vertically liftable in the lower platen frame by means of an expansible envelope therebetween. An upper platen frame on the base supports a heated upper platen for movement toward and away from the lower platen. A rotatable cam on the base is effective to lift the upper platen, and a bail on the base is effective to hold the upper platen against lifting above a chosen point. Both platens are centrally supported for expansion in two directions away therefrom, and the lower platen is made flexible by a number of transverse gaps therein.
